Physarum polycephalum is a slime mould with a complex life cycle, showing a great adaptability to environmental changes. It has an adaptive network of veins, which transport the endoplasmatic fluid from food sources to the different regions of the slime mould body, and whose geometry and adaptability are responsible for growth and motility [1]}. The veins walls of the network show rhythmic transverse oscillations, regulated by food sources and other external stimuli, [2]} and [3]}. Despite lacking any kind of neural circuit, Physarum shows a high-level behaviour, where, for example, the choice of the shortest path between food sources in a maze has been observed [4]}. Moreover,
in the presence of multiple food sources, Physarum can build networks with a great compromise between production cost, transport efficiency and fault tolerance
[5]}.
The main biochemical and physical mechanisms responsible by the rhythmic behaviour and the movements of Physarum is a challenging problem and has not been identified [6]}.
